6. INSPECT UNDERCUT DEPTH

Check that the undercut depth is clean and free of foreign materials. Smooth out the edge.

Standard undercut depth: 0.6 mm (0.24 in.) Minimum undercut depth: 0.2 mm (0.008 in.)

If the undercut depth is less than minimum, correct it with a hacksaw blade.

7. INSPECT FIELD COIL FOR OPEN CIRCUIT

Using an ohmmeter, check that there is continuity between the lead wire and field coil brush lead.

If there is no continuity, replace the field frame.

8. INSPECT FIELD COIL FOR GROUND

Using an ohmmeter, check that there is no continuity between the field coil end and field frame.

If there is continuity, replace the field frame.

9. INSPECT BRUSH LENGTH

Using a vernier caliper, measure the brush length. Standard length: 13.5 mm (0.531 in.) Minimum length: 8.5 mm (0.334 in.)

If the length is less than minimum, replace the brush holder and field frame.

10. INSPECT BRUSH SPRING LOAD

Take the pull scale reading the instant the brush spring separates from the brush.

Standard spring installed load: 17.6 - 23.5 N (1.79 - 2.39 kgf, 4.0 - 5.3 lbf) Minimum spring installed load: 11.8 N (1.2 kgf, 2.6 lbf) If the installed load is not as specified, replace the brush springs.

11. INSPECT BRUSH HOLDER INSULATION

Using an ohmmeter, check that there is no continuity between the positive (+) and negative (-) brush holders. If there is continuity, repair or replace the brush holder.

12. INSPECT GEAR TEETH

Check the gear teeth on the pinion gear, idle gear and the clutch assembly for wear or damage.

If damaged, replace the gear or clutch assembly.

If damaged, also check the drive plate ring gear for wear or damage.

13. INSPECT CLUTCH PINION GEAR

Rotate the pinion gear clockwise, and check that it turns freely. Try to rotate the pinion gear counterclockwise and check that it locks.

If necessary, replace the clutch assembly.

14. INSPECT REAR BEARING

Turn each bearing by hand while applying inward force. If resistance is felt or the bearing sticks, replace the bearing.

15. INSPECT FRONT BEARING

Turn each bearing by hand while applying inward force. If resistance is felt or the bearing sticks, replace the bearing.

16. DO PULL-IN COIL OPEN CIRCUIT TEST

Using an ohmmeter, check that there is continuity between terminals 50 and C.

If there is no continuity, check and replace the magnetic switch.

17. DO HOLD-IN COIL OPEN CIRCUIT TEST

Using an ohmmeter, check that there is continuity between terminal 50 and the switch body.

If there is no continuity, check and replace the magnetic switch.
